What compressor delivery does your operation need?
Add up consumers according to duty cycle and simultaneous operation. Also check possible full simultaneous demand.

How we calculate
Method: Sum of rated demands × duty cycle × simultaneity, then reserve. Full simultaneous demand without these reductions is shown separately. Flows at 1.01325 bar abs and 20 °C.
Assumptions and limitations: Duty cycle and simultaneity must not reduce the same effect twice. An average does not cover short peaks without storage. A motor cannot be sized accurately from flow alone.

Method version 1.0. Standard references verified in the ISO catalogue; the physical balances are not calculations prescribed by ISO. Before final design, we will verify actual operating and catalogue data.
